Perhaps you should try some spelling variations:
savings cross » savings groups, savings access, savings group
wang liang » wang yang
along what » along who, wrong what
liang yan » liang dan, liang tan, liang ying
oder cost » der cost, lower cost, power cost
yan oder » man oder, kann oder, ein oder

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang liang yan oder cost savings cross ((along what) OR (log what)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang yan oder cost savings cross ((along what) or (log what)) ;*.
